Defined as operating under the influence of a drug or alcohol. There are many factors that contribute to making this a very difficult question and many things have to be taken in to consideration before a judgment can be passed. OUI is a common acronym that stands for operating under the influence. The word “operating†is actually more encompassing (and more accurate) than “driving†because almost all states make it illegal to “operate or be in actual physical control†of a motor vehicle while legally impaired. San Diego DUI laws are written as such that you can be sitting in your car, pulled off to the side of the road, with the engine running and the car in park, and asleep, yet still be arrested and charged with DUI, DWI or OUI. The states that have OUI as their acronym are Maine, Massachusetts, and Rhode Island. OWI is another acronym used for driving crunk charges, or operating while intoxicated. Similar to OUI, the operative word is “operatingâ€. Wisconsin is the largest state using this acronym. OMVI (operating a motor vehicle while intoxicated) is an acronym used in Ohio from time to time, but they also use DUI.
